I beleive we have something which is more practical and <br />suitable for our purpose. <br />Snowmass has decided to use the existing concrete pads we poured for <br />the original weirs and purchase pre-fabricated two foot Parshall Flumes to <br />place on these pads. These flumes will be removed when the flow in the creeks <br />exceed 30 cfs. When spring runoff has peaked and the flow returns to 30 cfs <br />Snomwass will re-install the flumes. When the flow has dropped to 5 to 10 cfs <br />Snowmass will install a removable V-notch weir on the flume. This will allow <br />us to measure extremely low flows accurately. <br />Snowmass is now checking into <br />contact you when we have a delivery <br />comments concerning this new plan, <br />mine office. <br />SJ:mgc <br />RECEIVED <br />JUL 1 C 1984 <br />MINED LAND RECLAMATION DIVISION <br />Celo.
